Giant Wood Wasp

Hi rik,
This is a Giant Wood Wasp,
Urocerus gigas, a species that is found in Eurasia as well as North America.  What appears to be a stinger is actually an ovipositor.  Because the larvae are wood borers, they can be spread and introduced to new locations by the shipping of wood products.  See BugGuide for additional information.

    I found one of these in Ontario, is that normal?

    Saw what looks like the photo with a little bit more yellow. Body about 2″ long with a stinger like appendage about 1″ long. Do these exist in Colorado?
